The A34 improvements project is exploring opportunities to reduce congestion and improve safety on the A34 between the M4 and M40.

We know that people want to see improvements to the A34, north and south of Oxford. Congestion on the road leads to unreliable journey times. This disrupts people’s lives and their travel plans for both business and leisure. 

Reducing congestion would give users better and more reliable journeys and make the road safer.
